Trait redox::ops::Drop [−] [src]

pub trait Drop {
    fn drop(&mut self);
}

The Drop trait is used to run some code when a value goes out of scope. This is sometimes called a 'destructor'.

Examples

A trivial implementation of Drop. The drop method is called when _x goes out of scope, and therefore main prints Dropping!.

struct HasDrop;

impl Drop for HasDrop {
    fn drop(&mut self) {
        println!("Dropping!");
    }
}

fn main() {
    let _x = HasDrop;
}

Required Methods

fn drop(&mut self)

A method called when the value goes out of scope.
